Additional Reading

The human body naturally produces CoQ10, and it can also be obtained through certain foods like meats, fish, and whole grains. However, its levels may decrease with age, certain health conditions, or as a side effect of some medications, especially statins, which are used to lower cholesterol. A decline in CoQ10 levels can affect the body's ability to produce energy and protect against oxidative damage.

This is where CoQ10 supplements come into play. These supplements are often used to address potential deficiencies and have been explored for a range of potential health benefits. One of the most commonly cited benefits of CoQ10 supplementation is its potential to support heart health. Some research suggests that CoQ10 can help lower blood pressure, reduce the risk of adverse cardiovascular events in those with heart diseases, and improve symptoms in individuals with congestive heart failure.

Another significant area of interest is CoQ10's potential as an antioxidant. The body is constantly under attack from free radicals, which are unstable molecules that can cause cellular damage. Antioxidants like CoQ10 can neutralize these free radicals, protecting cells from oxidative stress. This antioxidative property is believed to confer various benefits, from slowing down the aging process to reducing the risk of certain chronic diseases.

CoQ10 supplements have also been examined for their potential in improving exercise performance, reducing headaches and migraines, improving skin health, and even supporting fertility. Some preliminary studies have even looked into CoQ10's role in neurodegenerative diseases, given its importance in cellular energy production.

The History of CoQ10 supplements

CoQ10, also known as ubiquinone and ubiquinol, was first discovered by American scientists in 1957. This fat-soluble substance plays a crucial role in the electron transport chain of aerobic cellular respiration, producing energy in the form of ATP, and acts as a powerful antioxidant.

Dr. Karl Folkers and Dr. Svend Aage Mortensen are two notable figures in the history of CoQ10 research. Dr. Folkers, known for his work in the biochemical study of disease conditions and the use of nutritional supplements, was instrumental in determining the structure of CoQ10 in 1958. He also conducted significant research into the effects of CoQ10 on heart failure, suspecting that a deficiency in CoQ10 could lead to energy starvation in heart muscle cells.

Dr. Mortensen, a Danish cardiologist and researcher, led the Q-Symbio study, a landmark clinical trial completed in 2014. This study provided crucial evidence supporting the use of CoQ10 as an adjunctive treatment for chronic heart failure. The trial focused on the patients’ disease symptoms, biomarkers, and long-term outcomes, such as hospitalization rates and mortality rates.

CoQ10 is essential for human growth and development, and the body's production of CoQ10 peaks in a person’s 20s and then decreases with age. Additionally, Dr. Folkers discovered that statin medications, used to inhibit cholesterol biosynthesis, also inhibit the biosynthesis of CoQ10. This led to the realization that CoQ10 deficiency could be a side effect of statin use, and supplementation might be necessary for some individuals.

In summary, the development and understanding of CoQ10 supplements have been significantly shaped by the work of Dr. Folkers and Dr. Mortensen, among others. Their research has highlighted the importance of CoQ10 in cardiovascular health and the potential need for supplementation, especially in older adults and those taking statin medications​

Ingredients of CoQ10 supplements

The ingredients of CoQ10 supplements can vary depending on the brand and specific product. However, the main ingredient is always coenzyme Q10 (CoQ10), which can be in two forms:

  • Ubiquinone This is the oxidized form of CoQ10 and is generally less expensive.
  • Ubiquinol This is the reduced form of CoQ10 and is considered more bioavailable, meaning it's more readily absorbed by the body. Some studies suggest it may also be more effective.

In addition to CoQ10, other common ingredients in CoQ10 supplements include:
  • Fillers and binders These help to give the supplement its shape and consistency. Examples include rice bran oil, gelatin, and vegetable glycerin.
  • Antioxidants These help to protect the CoQ10 from degradation. Examples include vitamin E and alpha-lipoic acid.
  • Excipients These are inactive ingredients that help with manufacturing, such as flavors, colors, and sweeteners.
